amaurophilia:Sexual preference for a blind or blindfolded sex partner or for having-sex in total darkness; may be due to religious guilt, low self-esteem, or feelings of inadequacy. (Most people are uncomfortable about having-sex under bright lights ; also, tactile stimulations reach greater sensitivity in semi or total darkness.) Etymology: From amaurosis , loss of vision or blindness, and philia , attraction. See also: lygerastia (arousal in darkness.)
